help about recompiling BRLTTY with another display

[Talksina boom boom]

hi,
I'd like to ask a question.
I have ubuntu (warty) distribution and installed by apt-get install, brltty 
3.4.1.
But now, I am going to change from my old Baum Vario 40, to a new Alva 
satellite series (USB).
I know the last version, 3.6 if I remember right, has the support.
my question is: can I compile it, and installing it, using my current 
working machine?
I mean, can I execute with my brltty 3.4.1 running and my old display 
connected in com1, the commands:
$ cd brltty-x.x.x
$ tar xzvf file
$ ./configure with options
$ make
# make install
or should I stop brltty daemon before installing the new one, or worse, 
remove the 3.4.1?
And...
does it copy automatically in init when running make install, if the 3.4.1 
is still there?
It's the first time I do something like that, I mean, compiling from a 
source, a package that runs automatically when system starts, and 
previously I had installed on debian way.
Tell me if I can do this operation without help from a sighted person, or 
not...
thanks in advance
